Camera

Q:

I have a Vivotek camera and set the advanced configuration of motion detection in camera's web UI manually, such as sensitivity and percentage setting. Why the advanced configuration of motion detection does not work?

A:

Please do the following:

Disable the motion detection on NVR’s setting page. Apply the settings and enable the function again.

Restart the VioStor.

Q:

I can manually specify the FTP server address of the camera in alarm settings page; however, the function does not work after entering a domain name. How to solve the problem?

For the ONVIF-compliant cameras what are not in QNAP’s compatibility list, please kindly use ONVIF to enable monitoring, recording and playback of this camera at this moment. Please make sure your NVR firmware is v3.5.0 build 4321 or later.

If the alarm recording of VioStor does not function, what should I do?

A:

Please login the administration page and go to Camera Settings-Alarm Settings. Make sure alarm recording is enabled for the camera.

When using Panasonic BB-HCM311 cameras, the camera firmware must be upgraded to v1.3 for alarm recording to work properly.

If VioStor is installed behind the router, VioStor would not receive the images to start alarm recording until you set up port mapping (virtual server) on the router and manually specify the alarm FTP server address of the camera in alarm settings page.

When alarm recording is enabled, make sure you have configured the number of days that alarm recordings will be retained in Camera Settings- Advanced Settings. Otherwise, the recordings may be overwritten.

Q:

If I adjust the fps of each channel as max, can the channels achieve 30 fps?

A:

No. The maximum fps VioGate-100/120, and VioCard-100 support is 50fps for 4-channel monitoring. When setting each channel’s fps as max, the maximum fps (50fps) will be shared by the four channels and each channel will achieve 10~15 fps.

Q:

I've set the video file length of Vivotek cameras on VioStor NVR as 1 minute and the frame rate as 1 fps. Why the recording files are all 2 minutes long?

A:

This is a camera limitation. Vivotek camera uses MPEG4 technology (group of picture) and the smallest unit of the video recording file is 120 frames. Therefore, if the frame rate setting is 1 fps, the video recording files are 2 minutes.

Q:

Why the estimated storage space for recording displayed in Recording Settings page is different from the actual value?

A:

This estimated value is for reference only. The actual disk space may vary according to the image contents, network environment and the performance of the cameras.

Q:

How to enable real-time digital watermarking on NVR? What's the limitation?

A:

To enable real-time digital watermarking, please follow these steps.

Camera Settings -> Recording Settings

Enable "Enable real-time digital watermarking"

If real-time digital watermarking has been enabled, performance of VioStor
NVR will be seriously affected, depending on your configuration.

When I connect a high megapixel camera from CMS live view, why I don't seem to have high megapixel quality?

A:

1. CMS receives and displays the streams sent from NVR. Right-click on each camera channel at CMS live view page, and choose "Quality Priority" to get the highesr resolution stream. (refer the snapshot)

Hardware

Initialize the external disk: You can go to “Device Configuration” -> “USB Disk” to initialize the external disk. The VioStor supports hard disks in FAT format.

The external disk must be larger than 10GB. VioStor supports external disks that are larger than 10GB currently.

Make sure the external hard disk is correctly connected to the “front” USB port of VioStor; this function will not work if the disk is connected to the rear USB port.

When the external disk is connected to the front USB port, wait until the USB LED glows in blue and then press the copy button. The data will be copied to the external disk immediately. The USB LED will blink in blue during the copying process. When the USB LED is off, copying is completed; you can safely remove the disk.

If the storage capacity of the external disk is insufficient, the log will be recorded in “Logs & Statistics” page.

As the backup file size can be very large, please wait patiently until the USB LED is off (backup completed), and then remove the external disk.

How to expand the storage capacity of VioStor-101 and NVR-104 by the eSATA port?

A:

You may refer to the steps below:

Back up the data on the VioStor to an external storage device.

Connect an eSATA disk to the eSATA port of the VioStor-101 and NVR-104.

Login the administration page and go to “Device Configuration”.

Create a RAID 0 disk volume or linear disk volume with the internal hard drive of the VioStor and the eSATA disk.

Warning: To create a RAID 0 disk volume or linear disk volume, the drives must be formatted and all the data will be cleared. Make sure you have backed up the recording data before formatting the drives.

Q:

Why VioStor takes too long to restart?

A:

When the server has been restarting for more than 5 minutes, please turn off the power and turn on the server again. If the problem persists, please contact the technical support.

Q:

Does VioStor support hot swapping?

A:

Yes. However, if the hard disks are working properly and recording is in process, do not hot swap the disks to avoid damage to the disks or recording files. Hot swapping can only be performed when a single disk crashes and there is no need to stop the recording.

Q:

When I do the "Quick Configuration," why the hard disk initiating progress is stucking?

If you are using the zooming function of Internet Explorer 7, the page may not be displayed properly. Please click F5 to refresh the page.

Q:

Why the live video of VioStor is not clear or smooth sometimes?

A:

The image quality may be restricted and interfered by the actual network traffic.

When there are multiple accesses to the camera or the VioStor server, the image quality will be reduced. And it is recommended to have three simultaneous connections to the monitoring page at maximum. For better recording performance, please do not open too many IE browsers to view the live video.

The same camera may be shared by multiple VioStors for recording at the same time. Please use dedicated cameras.

Q:

In the monitoring page of VioStor, if I unable to view live video on one of the cameras, what should I do?

A:

If the IP address, name and password entered in the camera configuration page are correct, You could use the Test function to verify the connection.

When the PC and the network camera are in the same subnet, while VioStor is in another one, you cannot view the monitoring screen from the PC. You can solve the problems by the following methods

Method 1: Enter the IP address of the network camera as the WAN IP in VioStor.

Method 2: Configure the router to allow internal access to the public IP address and the mapped ports of the network cameras.

Q:

When I enter preset point name in far east languages, it will show scrambled characters. What should I do?

A:

If you enter preset point name in far east language, please select UTF-8 on character encoding.

Q:

There is a large number of "Re-launch process [upnpd]" logs in the Event Logs. Why?

A:

The gateway setting is incorrect and the UPNPd process cannot be started correctly.

Q:

I've installed the VioStor behind the router or firewall and set up port mapping (virtual server) on the router. However, I still couldn’t access the VioStor. What should I do?
